entity-framework - Why am I getting Internal .NET Framework Data Provider error 1025 when passing Method to where?

Question

I have a method that takes a generic TEntity which is overriden. It's signature is as follows:

public virtual Expression<Func<AclProject, bool>> ProjectFilter(params TEntity[] objs)
    {
        return (p) => objs.Select(o => o.ID).Contains(p.ID);
    }

I then filter a query based on this:

from p in db.SomeDbSet where db.AclProjects.Where(ProjectFilter(p)).Any() select p

This results in a 1025 error. (note that it doesn't matter what the body of the ProjectFilter is, the error still occurs.

Any ideas why?

Thanks!
